Sample GSM2696782 Query DataSets for GSM2696782
Status Public on Jan 31, 2019
Title miRNAs from spent media of flight cells, Osteogenic medium, biological replicate 2
Sample type SRA
 
Source name hBMSCs on board the ISS cultured in osteogenic medium
Organism Homo sapiens
Characteristics cell type: bone marrow mesenchymal stem cells
location: on board the ISS
medium: osteogenic
rna fraction: miRNAs from exosomes (from spent media)
Growth protocol Standard Medium (SM): DMEM (Dulbecco’s Modified Eagle’s medium) supplemented with 12.5 mM HEPES, 10 U/mL heparin, 200 mM glutamine, 500 μg/mL streptomycin sulphate, 600 μg/mL penicillin.
Osteogenic Medium (OM): SM added with 0.1 M ascorbic acid, 10 mM b-glycerophosphate, and 10-8 M 1,25(OH)2D3 (Vit D3).
Extracted molecule total RNA
Extraction protocol We used the exoRNeasy Serum/Plasma Midi Kit for miRNAs extraction from exosomes
The presence and the integrity of small RNA was assessed using an Agilent Bioanalyzer
HiSeq Rapid SBS kit v2
 
Library strategy miRNA-Seq
Library source transcriptomic
Library selection size fractionation
Instrument model Illumina HiSeq 2000
 
Description FMOM_2_Exhmed_1
miRNA
Data processing Pre-processing: Sequencing adapters removal performed with Trimmomatic (v0.32)
Pre-processing: reads in the size range of 18-50 nucleotides were selected and used for downstream analysis
Mapping: mapped against mature miRNAs in the mirBase (version 21) using BWA tool (command bwa aln; v0.7.5a)
Feature count: miRNAs expression counts were obtained with samtools (z1.2)
Differential expression analysis: differential expression analysis was performed using the edgeR (Bioconductor version 2.13). Counts were normalized and differential expression was inferred using the negative binomial distribution and a shrinkage estimator for the distribution variance of the counts.
Genome_build: mirBase: r21 mature RNA
Supplementary_files_format_and_content: raw count of reads mapping to different miRNAs for each sample
